The feasibility of the MVN hydroformylation route has been demonstrated, and a detailed study has been reported on the key hydroformylation step. The roles of the catalyst, ligands, and solvents, as well as the effect of reaction conditions on the reaction rate and regioselectivity of the product 2-MNP, have been investigated. With Rh(CO)2(acac) as a catalyst and dppe as a ligand, &amp;gt; 98% selectivity to 2-MNP (an important precursor to D,L-naproxen) has been achieved. A possible mechanism to explain the variation in regioselectivity with Rh(CO)(2)(acac) as a catalyst and dppe as a ligand has been discussed. The kinetics of the hydroformylation step has been investigated and a rate equation has been proposed. The second step in the proposed route for naproxen-the oxidation of 2-MNP to 2-(6-methoxynaphthyl) propanoic acid (2-MNPA, or naproxen) - has been studied using Na2WO4 as a catalyst and tetrabutyl ammonium hydrogen sulfate (TBAHS) as the phase-transfer catalyst with H2O2 as the oxidant for the first time. Screening of the catalysts that consisted of the early transition metals, such as salts of tungsten, vanadium, and molybdenum showed that Na2WO4 gives the best performance for the oxidation step with &amp;gt; 80% selectivity to 2-(6-methoxynaphthyl)propanoic acid (2-MNPA/naproxen). This study would be valuable in developing a new environmentally benign route for naproxen synthesis.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">25</style></issue><work-type><style face="normal" font="default" size="100%">Article</style></work-type><notes><style face="normal" font="default" size="100%">Joint 6th International Symposium on Catalysis in Multiphase Reactors/5th International Symposium on Multifunctional Reactors (CAMURE-6/ISMR-5-), Pune, INDIA, JAN 14-17, 2007</style></notes><custom3><style face="normal" font="default" size="100%">Foreign</style></custom3><custom4><style face="normal" font="default" size="100%">2.567</style></custom4></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Atla, Shashi B.</style></author><author><style face="normal" font="default" size="100%">Rajurkar, Kalpendra B.</style></author><author><style face="normal" font="default" size="100%">Kelkar, Ashutosh A.</style></author><author><style face="normal" font="default" size="100%">Chaudhari, Raghunath V.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Kinetics of arylation of 3-bromo-benzophenone with n-butylacrylate using NC palladacycle catalyst</style></title><secondary-title><style face="normal" font="default" size="100%">Journal of Molecular Catalysis A-Chemical</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">Arylation</style></keyword><keyword><style  face="normal" font="default" size="100%">Heck reaction</style></keyword><keyword><style  face="normal" font="default" size="100%">kinetics</style></keyword><keyword><style  face="normal" font="default" size="100%">Palladacycle</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2009</style></year><pub-dates><date><style  face="normal" font="default" size="100%">AUG</style></date></pub-dates></dates><number><style face="normal" font="default" size="100%">1-2</style></number><publisher><style face="normal" font="default" size="100%">ELSEVIER SCIENCE BV</style></publisher><pub-location><style face="normal" font="default" size="100%">PO BOX 211, 1000 AE AMSTERDAM, NETHERLANDS</style></pub-location><volume><style face="normal" font="default" size="100%">309</style></volume><pages><style face="normal" font="default" size="100%">111-116</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;The kinetics of arylation of n-butylacrylate (n-BA) with 3-bromo-benzophenone (BBP) using a monomeric palladacycle complex [Pd(ppy)(PPh(3))(OTs)](ppy=2-phenylpyridine) catalyst has been studied. The effect of concentration of the substrate, base (NaOAc), and catalyst was studied at three different temperatures (413-433 K). The rate was found to be first order with respect to catalyst, first order tending to zero order with respect to n-butylacrylate and NaOAc concentrations. The rate passed through a maximum with variation of BBP concentration. The observed results have been explained on the basis of formation of Pd species (PdX(2), PdX(3)(-), PdX(4)(2-), and Pd(2)X(6)(2-)) which are inactive for the Heck reaction. Various empirical rate equations were considered to fit the rate data and the best fitting model has been selected. The rates predicted by model were found to be in good agreement with the observed experimental data. (C) 2009 Elsevier B.V.

The model consists of mass and heat balance equations for the gas and liquid phases and the catalyst particle. The model equations consisted of partial differential equations (PDE) which were converted to ordinary differential equations (ODE) by using finite difference relationships for the spatial derivatives and the ordinary differential equations for the time derivatives (Numerical Method of Lines-NMoL). The model was applied to describe the dynamic behaviour of bubble column slurry reactor during the hydroformylation of 1-decene on Rh/C catalyst. Model simulations were performed to obtain a meaningful path to steady state and to reproduce the other characteristics of the dynamic behaviour of the reactor. Under given conditions, the reaction required approximately 3750 seconds to reach the steady state concentrations at various reactor positions. It was observed with increase in the fluid velocities, the dynamics of the system was altered to 2500 seconds to reach the steady state condition. The effect of axial dispersion on the substrate concentration and the temperature rise along the reactor was further studied and discussed.&lt;/p&gt;</style></abstract><notes><style face="normal" font="default" size="100%">International Conference on Modeling, Optimization, and Computing, Durgapur, INDIA, OCT 28-30, 2010</style></notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>47</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Upkare, Makarand M.</style></author><author><style face="normal" font="default" size="100%">Rajurkar, Kalpendra B.</style></author><author><style face="normal" font="default" size="100%">Gupta, Pankaj R.</style></author><author><style face="normal" font="default" size="100%">Jaganathan, Rengaswamy</style></author></authors><secondary-authors><author><style face="normal" font="default" size="100%">Paruya, S.</style></author><author><style face="normal" font="default" size="100%">Kar, S.</style></author><author><style face="normal" font="default" size="100%">Roy, S</style></author></secondary-authors></contributors><titles><title><style face="normal" font="default" size="100%">Mathematical modeling and simulation of bubble column reactor for aerial liquid phase cyclohexane oxidation</style></title><secondary-title><style face="normal" font="default" size="100%">International Conference on Modeling, Optimization, and Computing</style></secondary-title><tertiary-title><style face="normal" font="default" size="100%">AIP Conference Proceedings</style></tertiary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">K-A Oil Selectivity</style></keyword><keyword><style  face="normal" font="default" size="100%">Mathematical modeling</style></keyword><keyword><style  face="normal" font="default" size="100%">substrate conversion and product yield analysis</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2010</style></year><pub-dates><date><style  face="normal" font="default" size="100%">OCT</style></date></pub-dates></dates><publisher><style face="normal" font="default" size="100%">Natl Inst Technol Durgapur; SERC, Dept Sci &amp; Technol; Caledonian Coll Engn; BRNS, Dept Atom Energy; DRDO, Minist Defence</style></publisher><pub-location><style face="normal" font="default" size="100%">2 Huntington Quadrangle, STE 1no1, Melville, NY 11747-4501 USA</style></pub-location><volume><style face="normal" font="default" size="100%">1298</style></volume><pages><style face="normal" font="default" size="100%">151-159</style></pages><isbn><style face="normal" font="default" size="100%">978-0-7354-0854-8</style></isbn><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">&lt;p&gt;Cyclohexane oxidation is an important but complex commercial reaction, wherein the desired product, K-A oil appears as an intermediates of the reaction sequence.

The rate showed a first-order dependence with respect to catalyst and camphene concentrations. The effect of partial pressure of hydrogen showed fractional order dependence. The plots of rate versus excess ligand, that is, (P(OPh)(3)) concentration and rate versus CO partial pressure passed through maxima and showed typical substrate/ligand inhibited kinetics.
